Subject [jira] Commented: (MYFACES-1881) UIViewRoot setId called on UIComponentClassicTagBase throws UnsupportedOperationException
Date Thu, 19 Jun 2008 16:55:45 GMT

    [ https://issues.apache.org/jira/browse/MYFACES-1881?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12606454#action_12606454
] 

Leonardo Uribe commented on MYFACES-1881:
-----------------------------------------

I have commented and call super.setId() on UIViewRoot, while we decide what to do with this
issue (let this with the exception break trunk, so nobody can use the snapshot). 

UIViewRoot should not have clientId, because is never used but have setId does not harm.

> The latest myfaces core 1.2.4-SNAPSHOT throws this exception, because setId was disabled.
> This is because javax.faces.webapp.UIComponentClassicTagBase try to set its id:
> We have two options here:
> 1. do not set its id on UIComponentClassicTagBase
> 2. call super.setId and super.getId properly on UIViewRoot.
> I don't know if there is side effects (a component without id? what happens when its
state is saved and restored?).
> Suggestions?
